Answer :
Sure! Let's tackle each part of the question step by step.
1. Working with Whole Numbers
(a) We need to make the number sentence `8 ☐ ☐ = 800` true. This involves either multiplying or dividing by 10, 100, or 1000. Let's try:
- If we use multiplication, 8 multiplied by 100 equals 800. So, the correct symbols are multiplication (`*`) and 100.
(b) We need to make `740000 ☐ ☐ = 740` true. This also involves either multiplying or dividing by 10, 100, or 1000. Let's try:
- If we use division, 740000 divided by 1000 equals 740. So, the correct symbols are division (`/`) and 1000.
2. Rounding Numbers
We will circle all numbers that round off to 60000. Rounding typically looks at the thousands place:
- 62495 rounds off to 62000 (not 60000).
- 54498 rounds off to 54000 (not 60000).
- 65000 stays 65000 (not 60000).
- 56002 rounds off to 56000 (not 60000).
- 67024 rounds off to 67000 (not 60000).
None of these numbers round to 60000.
3. Calculations
(a) For the addition: [tex]\(274561 + 367238 = 641799\)[/tex].
(b) For the subtraction: [tex]\(4672 - 3937 = 735\)[/tex].
(c) For the multiplication: [tex]\(3458 \times 43 = 148694\)[/tex].
(d) For the division: [tex]\(6624 \div 18 = 368\)[/tex].
4. Multiplication of Numbers
We need to find the product of these numbers: [tex]\(8 \times 15 \times 22 \times 29\)[/tex].
The calculated result is 76560.
These are your solutions for each part of the question. Let me know if you have any further questions!
